Abstract

Stored products are attacked by many insect groups including more than 600 species of beetle pests, 70 species of moths and about 355 species of mites causing quantitative and qualitative losses. For this reason, stored product pests are most important factors to damage agricultural crops in all stores of the world. Tribolium confusum Duval (Col.: Tenebrionidae) and Callosobruchus maculatus Fabricius (Col.: Chrysomelidae) are destructive pests of stored products in most region of Iran. Botanical products such as plant extracts and essential oils are generally favored for insect pest’s management because of their less harmful compounds affecting on non-target organisms and human health. Many plant compounds have shown a broad spectrum of activity against insect pests ranging from toxicity, antifeedant, repellent, oviposition deterrent and growth regulatory. In the current study, toxicity and repellency of ethanolic extracts of Anagyris foetida L. leaf and seed have been evaluated against C. maculatus and T. confusum at 27±1 °C and 60±5% Relative Humidity. Toxicity of leaf and seed extracts were investigated Filter paper method and mortality was recorded 24 h post treatment. Each experiments war replicated 4 times and in every replication 20 insect was used. Also, the chemical compositions of extracts were determined by gas chromatography-mass spectrometry (GC-MS). Furthermore, data analysis of experiments was done by Polo Plus and SPSS software. The probit analysis showed that the seed extract toxicity (LC50 value) of A. foetida on T. confosum and C. maculatus were 419.65 (377.54- 463.98) μgL-1 and 540.067 (490.21- 589.54) μgL1, respectively. Also, the leaf extract toxicity (LC50 value) of A. foetida on T. confosum and C. maculatus were 730.404 (666.38-794.83) μgL-1 and 663.684 (613.74- 714.23) μgL1, respectively. These results indicated that seed extract toxicity is more than leaf extract. Also, the result of repellency experiments showed that the seed extract has m
